摘要:

A great deal of attention has been given to the use of expert systems in solving manufacturing problems by software development experts as well as application experts. However, the evaluation of expert systems in manufacturing applications has received very little attention in the literature. Whether or not an expert system is justified for a particular manufacturing environment depends on the expert system's effectiveness on both the manufacturing problem and the problem environment.

摘要:

The relationship between the internal rate of return (IRR) and the return on investment (ROI) as criteria for evaluating the profitability of investment is presented in this paper. The relative behavior of the ROI under several definitions is analyzed. While certain simplifying assumptions are made, the model is comprehensive, flexible and useful for examining the impact of changes in policy and environmental variables on the ROI. Under a certainty framework, the ROI is determined by company's policies (dividends and leverage) business environment (interest rate, IRR, and taxes); and the investment horizon and depreciation. Mainly due to the reinvestment rate assumption implicit in the ROI, the most pervasive of all these factors is the dividend policy,𝛗. Given the reinvestment rate assumption and different revenue and investment measures, the ROI is not a good indicator of the IRR. The introduction of uncertainty in cash flows which need to be analyzed under a probabilistic framework, perhaps using numerical analysis or simulation methods, is suggested for extending this model and to develop further research in this area.

摘要:

High technology investments are a rapidly growing segment of business capital expenditures. The questionnaire responses presented in this paper provide information on the capital investment decision processes currently being used for high technology projects. Respondents indicate that the capital evaluation techniques used to justify high technology investments are similar to those used for other types of capital projects and that high-tech projects must meet normal requirements for project acceptability. Respondents specified that a wide variety of factors, some quantified and some not quantified (such as quality control and reduced lead time), are included in their decision process. While there is general satisfaction with the procedures used for project justification, the relative newness of these investments suggests that there is a need to gather more detailed information about this type of capital decision.
